EU don't, but you need to make sure about the country in which you operated the crane as each EU country has its own laws and EU directives are not laws.

I doubt you can be held responsible in such a case unless you are a civil engineer enabled to publish such designs and you did so by stating that those designs are in fact good to go.

If I build my own crane and die or, worse, kill somebody operating it I am the only one responsible even if my uncle told me how to do so.
